Fire Extinguisher Residue Cleanup

There are seven common types of fire extinguishers. Two of them do not have to be cleaned after use. Those two are:

  1. Water – Just dry the area and proceed with your restoration.
  2. Carbon Dioxide – Carbon Dioxide removes oxygen in the area to suffocate a fire. Carbon dioxide extinguishers leave no residue and are commonly used in computer rooms and food storage areas. Since they leave no residue, you can go straight to the restoration work.

The other five types of fire extinguishers require thorough cleaning to be performed after use. Those five and what they are made of are listed here. Out of these five, the halotron extinguisher is the only one that requires very different cleaning procedures. The other types can all be cleaned with the procedures under "Dry Chemical Fire Extinguisher Residue Clean Up."

  1. Halotron - Some older fire extinguishers use halon as the extinguishing media. Halon was common in older fire extinguishers because it leaves no VISIBLE residue. Halon extinguishers are no longer being produced
  2. Multi-Purpose Dry Chemical - Typically uses a chemical agent called mono ammonium phosphate
  3. Regular Dry Chemical – Uses a sodium-bicarbonate-based dry chemical agent
  4. Foam
  5. Purple K Dry Chemical – Uses a potassium-bicarbonate-based dry chemical agent
